NOTES NOTES --- # xaringan - Press `h` or `?` to see the possible shortcuts you can use in remark.js. - You can see all the goodies like this (hint press `p`). - Check out more in-depth tutorial [here](https://slides.yihui.name/xaringan/#1) --- ## Why xaringan/remark.js? <i class="fas fa-check-circle fa-pull-right "></i> - Printing (in Google Chrome) is a lot more reliable for xaringan/remark.js - The customisation of the CSS and using it is a lot easier in xaringan/remark.js - You almost never need to write any manual HTML chunks (e.g. `<div style="text-align: center;"></div>`) - With remark.js' Markdown, you can add arbitrary CSS classes to elements using syntax `.className[elements]`, which is very handy compared to `<span class="className"></span>` - You can write slide notes under three question marks `???`. These notes are only displayed in the presentation mode, and only the speaker can see these notes. - The keyboard shortcuts: press keys like `P` (presentation mode), `C` (clone slides to a new window, useful for presentation mode), `B` (black out), `M` (mirror the slide), and `H` (help), etc. More: [yihui.name/en/2017/08/why-xaringan-remark-js/](https://yihui.name/en/2017/08/why-xaringan-remark-js/) --- # YAML, Slides and Notes The `YAML` is the head of the document in which one defines all the settings and certain aspects as author, title, date. To start a new slide use three dashes `---` on a new line with no trailing white space. If the dashes aren't on their own line or there's a white space after it won't work. ``` --- ``` If we want to change the style of a slide we can do so with the option `class` directly after the three dashes for a new slide. ``` --- class: columns-2 ``` Similar to start a new line use three questionmarks `???` on a new line with no trailing white space, to take notes for your presentation. ``` ??? ``` --- # Embaded `R` Code .font70[ With Rmarkdown/xaringan `R` code can directly implemented. There are two ways to implement R Code. If we want to use r code *inline*, we wrap the command around .ilr[r ]. For example if we want to write some continuous text which tells us how many variables the `mtcars` data set has, we just write .ilr[r dim(mtcars)[2]] (`mtcars` has 11 variables). For bigger outputs, for instance plots or a summary of a `lm` object, there exists an other method. We start a new line with .olr[{r}] and start in the next line with our `R` code, to close the `R`-chunk we just write .olr[ ]. Example: .pull-left[  ] .pull-right[ ```r ggplot2::ggplot(mtcars, aes(x = mpg, y = hp))+ geom_point()+ theme_minimal() ``` <!-- --> ]] .pull-down[ More information how to use and format `R` output in a `R Markdown` can be found on the [RStudio](https://rmarkdown.rstudio.com/lesson-1.html) site. ] --- # Scrolling `R` Output If you just want a section of the output to be scrollable (not the whole page). You need to define how many lines you want the "box" to show. There are classes for `.scroll-box-8[]` for 8 lines, `.scroll-box-10[]` for 10 lines, ... , `.scroll-box-20[]` for 20 lines. ### Example `.scroll-box-8[]` .scroll-box-8[ ```r swiss[,1:3] ``` ``` ## Fertility Agriculture Examination ## Courtelary 80.2 17.0 15 ## Delemont 83.1 45.1 6 ## Franches-Mnt 92.5 39.7 5 ## Moutier 85.8 36.5 12 ## Neuveville 76.9 43.5 17 ## Porrentruy 76.1 35.3 9 ## Broye 83.8 70.2 16 ## Glane 92.4 67.8 14 ## Gruyere 82.4 53.3 12 ## Sarine 82.9 45.2 16 ## Veveyse 87.1 64.5 14 ## Aigle 64.1 62.0 21 ## Aubonne 66.9 67.5 14 ## Avenches 68.9 60.7 19 ## Cossonay 61.7 69.3 22 ## Echallens 68.3 72.6 18 ## Grandson 71.7 34.0 17 ## Lausanne 55.7 19.4 26 ## La Vallee 54.3 15.2 31 ## Lavaux 65.1 73.0 19 ## Morges 65.5 59.8 22 ## Moudon 65.0 55.1 14 ## Nyone 56.6 50.9 22 ## Orbe 57.4 54.1 20 ## Oron 72.5 71.2 12 ## Payerne 74.2 58.1 14 ## Paysd'enhaut 72.0 63.5 6 ## Rolle 60.5 60.8 16 ## Vevey 58.3 26.8 25 ## Yverdon 65.4 49.5 15 ## Conthey 75.5 85.9 3 ## Entremont 69.3 84.9 7 ## Herens 77.3 89.7 5 ## Martigwy 70.5 78.2 12 ## Monthey 79.4 64.9 7 ## St Maurice 65.0 75.9 9 ## Sierre 92.2 84.6 3 ## Sion 79.3 63.1 13 ## Boudry 70.4 38.4 26 ## La Chauxdfnd 65.7 7.7 29 ## Le Locle 72.7 16.7 22 ## Neuchatel 64.4 17.6 35 ## Val de Ruz 77.6 37.6 15 ## ValdeTravers 67.6 18.7 25 ## V.
